MAYER, OF SPRINGFIELD, OHIO, AND ONE-THIRD TO DENNIS T. IGOU', OF SPRING- FIELD, OHIO HUMIIJIFIER Application filed January 6, 1930. Serial No. 418,822.

My invention relates to a humidifier.

It is the object of my invention to provide a humidifier which is constantly supplied with a predetermined amount of fluid to give a predetermined humidity content.

It is a further object of my invention to provide a construction that is particularly adaptable to incubators for supplying humidity thereto. I

It is my object to provide a humidification apparatus in which surplus moisture is automatically extracted before the air makes its exit from the apparatus.

Referrin r to the drawings Figure 1 a side elevation of the complete apparatus. I

Figure 2 is a vertical section therethrough. Figure 3 is a transverse section therethrough. I

Referring to the drawings in detail 1 is a motor traveling at preferably 1,750 B. P. M. and supplying the current through the line 2 which is controlled by the switch 3. The armature shaft 4 of this motor is connected as to suitable gearing in the gear box 5 for increasing the speed of the shaft 6. The speed may range from 2,000 to 4,000 B. P. M. On the end of the shaft 6 is a disc 7 which turns within the water 8 in the supply tank 9. Projecting laterally from the disc 7 and pass ing successively through the water 8 are a series of pins l0 which may be formed 1n any desired manner. These pins when traveling at a high rate of speed, in conjunction with the disc 7 which picks up a fihn of water serve to draw a thin film of water or water in finely divided condition from the pool of water and the pins 10 further serve as blades for moving air through the incoming passageway 11 over the surface of the water 8 through the opening 12 in the partition 13 and thence upwardly through the passageway 14 where the moisture-laden stream of air impinging against the curved wall 15 causing the deposit of that moisture which is thoroughly incorporated with the air stream in a f0 and thence the air reverses its direction su stantially 360 going doubt-- lessly on the inside of the passageway 16 at right angles, making its exit through the passageway 18. The end of this passagetainer 24 is supported on a bracket 25 with its mouth 26 beneath the surface of the water 8 in the reservoir container 9 so that the water will be maintained at a constant level as it can freely pass through the opening 27 in the wall 28 and opening 12 in the wall 13.

It will be understood that the disc 7 is the primary means for drawing the water out into a thin film and the pins 10 a rimary means for moving the air over the 1m and incorporating the moisture and air one with the other.

It will be understood that I desire to comprehend within my invention such modifica-v tions as may be clearly embraced within the scope of my claims and invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a humidifying apparatus, a tank having a horizontally disposed pool of liquid, a, vertically disposed passageway terminating at the surface of the liquid, a second vertically disposed passageway parallel there to communicating by a restricted passageway over the surface of the liquid with the first-mentioned vertical passageway, means in the second passageway for picking up a film of liquid, means associated therewith for drawing air through said passageway over said film of liquid and a third vertical passageway parallel to the secondhaving a discharge opening at the bottom.

2. In a humidifying apparatus, a tank having a horizontally disposed pool of liquid, a vertically disposed passageway terminating at the surface of the liquid, a second vertically disposed passageway parallel thereto communicating by a restricted passageway over'the surface of the liquid withthe first-mentioned vertical passageway, means in the second passageway for pickin up a film of liquid, means associated therewith for drawing air through said passageway over said film of liquid, a third vertical passageway parallel to the second having a discharge opening at the bottom and means for returning of the surplus moisture entrained with the air back to the original source of supply.

3. In a humidifying apparatus, a tank having a horizontally disposed pool of liquid, a vertically disposed passageway terminating at the surface of the liquid, a second vertically I disposed passageway parallel thereto communicating by a restricted passageway over the surface of the liquid with the first-mentioned vertical passageway, means in the second passageway for picking up a film of liquid, means associated therewith for drawing air through said passageway over said film of liquid, a third vertical passageway parallel to the second having a discharge opening at the bottom, means in said second and third passageways for returning of the surplus moisture entrained with the air back to the original source of supply and means for maintaining a constant level of liquid in said source of supply.

In testimony whereof, I afiix my signature.

FRANK E. STOVER.
